Sentence examples for arithmetic formulae from inspiring English sources

To determine the relative quantification of gene expression, comparative cycle of threshold (Ct) method with arithmetic formulae (2−ΔΔCt) was used [ 16].

Spectroscopic examination shows that every element has its characteristic set of spectral lines, and the discovery by the Swiss mathematician Johann Jakob Balmer of a simple arithmetic formula relating the wavelengths of lines in the hydrogen spectrum (1885) proved to be the start of intense activity in precise wavelength measurements of all known elements and the search for general principles.

There are various arithmetic formulas used for the assessment of IVC collapse, the most common being the collapsibility index [(IVC max diameter- IVC min diameter)/IVC max diameter].

Using an arithmetic formula [15] denoting a finite sum of cosines given by ∑ k = 0 n cos ( k a + b ) = sin n + 1 2 a cos a n 2 + b sin a 2, where n ∈ { 1, 2, … }, (25).

Optimal implementation result and high speed of operation is achieved by direct event driven architecture that allows to branch the process to several different calculation depending on external events This unit offers easy modification of arithmetic formulas either statically or in a runtime.

Relative gene expression was calculated using the mean values obtained with the arithmetic formula ΔΔCt (Applied Biosystems).

Data were collected at step 2. The results were obtained using the comparative Ct method and the arithmetic formula 2−ΔΔCt.

Relative expression was determined by the comparative CT method of relative quantification (RQ) and calculated with the arithmetic formula 2−ΔCt, where ΔCt is the normalized signal level in a sample.

Relative quantification was performed using the Comparative CT (threshold cycle) method which uses the arithmetic formula 2−ΔΔCT to represent the amount of target gene, normalized to an endogenous reference (GAPDH, in our case) and relative to a calibrator sample.

Briefly, this method uses arithmetic formulas to determine relative quantification.

Relative mRNA levels of gene expression were determined using the threshold cycle (CT) and arithmetic formulas.
